[THE CONTENTS OF FORMATION OF THE ELECTRIC WELDING ANASTOMOSIS OF STOMACH AND SMALL INTESTINE].

The character and sequence of changes in the tissues structure of the gastrointestinal walls under the impact of the impulse and constant delivery of electric pressure with frequency 440 kHz were studied. The investigation object was squeezed, using the force, measured from 2 to 6 N/mm2. The ЕКВЗ-300 «Patonmed¼ apparatus was used as a source of supply. Еlectric parameters of the process was fixed, using the analogue-numerical digital converter LCard E20-10 and laboratory oscilloscope Tektronix TDS 3014C. There was established, that electric conjunction of stomach and small intestine include three elements: destroying and disappearance of mucosa, connective tissue and membranes; fusion of the collagen fascicles and the smooth muscle cells; the loss of the collagen fascicles and the smooth muscle structure and creation of homogenous еlectric welding suture. The first two elements of the electric welding anastomosis are occurring simultaneously, but not dependent one from the other. At the welding suture completion the nondestructive changes of the tissues are spreading on a distance not more than 1 mm beyond the borders of the electrods apposition.
